ALBERT L. PIPES, OF SAEULPA, OKLAHOMA.

RAILWAY-SWITCH POINT.

aromas.

To all whom it may concern Be it known that I, ALBERT L. PIPES, a citizen of the United States, residing at Sapulpa, in the county of Greek and State of Oklahoma, have invented certain new and useful Improvements in Railway- Switch Points, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in railway switch points and the primary object of the invention is to provide a device of this character which will, at all times, be free from snow and ice and one which may be said to be nonsplittable.

A further object of the invention resides in providing a movable switch point which operates vertically of the rails and still another object of the invention resides in providing a device which is simple and durable in construction, inexpensive to manufacture and one which will be very efficient and useful in operation.

With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings forming a part of this application, Figure 1 is a plan view of a track section showing my improved switch point applied to use in connection therewith. Fig. 2 is a transverse section therethrough as seen on line 22, Fig. 1. Fig. 3 is a longitudinal section through a track showing the switch point in its raised and effective position. Fig. 4% is a similar view showing the switch point in its lowered and inefi'ective position. Fig. 5 is a transverse section as seen on line 5-5, Fig. 3. Fig. 6 is a similar view as seen on line 66, Fig. 4.

In describing my invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates a rail of the usual type mounted on ties 2 and forming with an additional rail, also mounted on said ties, a complete track section. A switch is arranged in connection with the track section and at a point adjacent the switch, the rail 1 is supported on a plate 3, which is carried. on said ties and also mounted on the plate at this point,

is a guard rail 4 of the usual or any preferred type.

My invention primarily contemplates the provision of a switch point in connection with this guard rail which is movable vertically of the rails, instead of laterally, as is usually the case and to this end, a pair of bars 5 and 6 are provided, the same being mounted one upon the other between the rails 1 and 4- and on the plate 3. The lowermost bar 6, which rests directly in contact with the upper face of the plate 3 is adapted to move longitudinally of the rails and a depending projection or tongue 7 formed on said bar and projecting through a slot 8 in the plate 8 affords a means whereby the movement of said bar 6 may be limited. The upper bar 5, on the other hand, is adapted for a slight vertical movement between the rails 1 and a and in order to pre. vent any possible longitudinal movement thereof, laterally extending pins 9 are provided onsaid rails 1 and 4, for introduction through vertical slots 10 in the bar 5 ad jacent its ends.

The upper face of the bar 6 is provided with a plurality of notches or offsets 11, the one wall of each of which is beveled or inclined, as shown at 12, while the opposite wall thereof is flat and vertical. The lower or inner face of the bar 5 is also provided with a plurality of notches or offsets 13 which are designed identical to the notches 11 and have the walls arranged adversely to the latter. The portions of the bars, between these notches have the inner opposed faces thereof flat and when the flattened portions of the bars rest one upon the other as clearly disclosed in Fig. 3 of the drawings, the switch point which may be said to be composed of said bars 5 and 6, is in its effective and operative position. In such position, the upper outer face of the bar 5 is for the greater portion of its length, flush with the upper face of the rail 1. It appears, from this construction, therefore, that when the lower bar 6 is moved longitudinally in one direction, the upper bar 5 will be permitted to descend so that said bar 5 will have its upper face below the upper face of the rail 1 and the notches of the bars and the portions therebetween, interlock as clearly shown in Fig. 4 of the drawings.

I have provided a means for the actuation of the lower bar 6, whereby to dispose the switch point to its effective and ineffective position and to this end, certain of the ties 2, adjacent the switch point are extended, as shown at 14, the same being connected by a transverse bar 15, whereby to form a substantial extension frame adjacent the switch point. Arranged on opposite sides of the plate 3, are the bearings 16 and mounted for oscillation therein, is a shaft 17 which has a crank portion 18 formed therein. This crank portion is connected with the depending tongue 7 on the lower bar 6 and this shaft is extended to the outer transverse bar 15 and connected with alever 19. It will thus be seen that this switch point maybe actuated by the throwing of the lever 19 in one direction or the other and I have provided a means to aid in the raising and lowering of the switch point as the lever is actuated. To this end, U- shaped plates 20 are secured to the upper bar 5 adjacent its ends and receive therein the lower bar 6. Slots 21 are provided in i the plate 3 at thepoints where these U- shaped plates 20 are provided and the under face of said bar 6 is provided with projections 22 which extend through these slots. The one face of each of the projections is beveled, as shown at 23 and these faces are adapted to engage the base portions of the U-shaped plates 20 to obviously aid in lowering the bar 5 as said lower bar 6 is moved longitudinally in one direction. It must be here stated also that the upper bar 5 is reduced in thickness from its upper face for a portion of its length, as shown at 2 1 and at the junction of this reduced portion with the depending portion of the bar, a beveled shoulder 25 is provided which forms the switch point proper and cooperates with a similar beveled shoulder formed on the guard rail 4:.

The lever 19 has the upper handle portion thereof pivoted in position, as shown at 26 an this pivoted portion is provided with a slot therein. The pivoted portion of the lever 19 is adapted to be bent downwardly, as shown in dotted lines in Fig. 2, at the extremities of the path of said lever and staples 27 carried on the guide through which said lever extends, are adapted to be received in the slot of said pivoted portion, when the latter is bent downwardly at the extremities of the path of said lever. The staples are adapted to project above the slot in the pivoted portion and thus permit a pad-lock or other locking means indicated at 28 to be engaged therewith. The lever is thus locked securely in its adjusted position.

From the foregoing description of the construction of my improved device, the operation thereof will be readily understood and it will be seen that I have provided an improved switch point which may be actuated at all times regardless of the snow and ice that may be on the ground and it will still further be seen that the same is simple and durable in construction, inexpensive to manufacture and one which will be-very efficient and useful in operation.

. While I have particularly described the elements best adapted to perform the func- I plate being provided with'slots at predeterinined points therein; of a switch point consisting of a pair of longitudinal bars ar ranged one upon the other betweensaid' main and guard rails, the contacting faces of said bars being provided with notches having opposite walls beveled coincident to one another, said upper bar being capable of vertical movement and the lower bar being capable of longitudinal movement. be-

tween said rails, projections formed on the lower face of said lower bar extending through the slots of said base plate, one face of each of said projections being beveled, U-shaped keepers carried onthe upper bar and encircling said lower bar,.said keepers being adapted to be engaged by the beveled faces of the projection when said lower bar is moved longitudinally in one direction,

and means to actuate said lower bar whereby to raise and lower the upper bar with respect to said rails.

In a railway switch, the combination with a main rail, a guard rail arranged in spaced relation thereto, and a baseplate for said rails having a plurality of slots therein arranged at predetermined points in the same; of a switch point composed of a pair of longitudinal bars arranged one upon the other between said main and guard rails,
